"Grab The City" is a challenge that wants you to extract the name of the city in a given sentence which the name is wrapped in a pair of square brackets in the end of the sentence.

// the commented line below (the regex to be exact) gets just the last word! which is wrong, my fault though, i didn't read the challenge corectly!
// let regex = try! NSRegularExpression(pattern: "(\\w+)(?!.*\\w)", options: [])
// the regex below get every matches in the sentence that is being wrapped in a pair of square brackets.
let regex = try! NSRegularExpression(pattern: "(?<=\\[)(.+?)(?=\\])", options: [])
// the "result" below is of type NSTextCheckingResult which is an array, since the challenge askes for the last match, and i couldn't get the last match through the regex, i ened up gtting the last match via the "last" item in the array.
let result = regex.matches(in: str, options: [], range: NSRange(location: 0, length: str.count)).last

// from line 11 to 18, is an alternative for getting the matches out of the result array, since it is an array (of type NSTextCheckingResult) you can iterate thtough it (loop though it)
// you can use each o
